Although Saint Irene performed many miracles during her life, let us mention only one. On great Feasts it was her habit to keep vigil in the monastery courtyard under the starry skies. Once, a nun who was unable to sleep left her cell and went into the courtyard. There she saw Abbess Irene levitating a few feet above the ground, completely absorbed in prayer. The astonished nun also noticed that two cypress trees had bowed their heads to the ground, as if in homage. When she finished praying, Irene blessed the trees and they returned to their upright position.
